To alZ whom it may concern:

Be it known that we, WALTER H. SABIN and HANs LARSON, citizens of theUnited States, residing at Crookston, in the county of Polk, State ofMinnesota, have invented certain new and useful Improvements in Scales;and we do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same. p

This invention relates to weighing scales, more particularly to scalesof relatively small size adapted to be carried in the pocket, anddesigned more particularly for weighing mail matter, and has for one ofits objects to simplify and improve the construction and increase theconvenience of devices of this charaoter.

lVith this and other objects in view, the invention consists in certainnovel features of construction hereinafter shown and described and thenspecifically pointed out in the Claim; and, in the drawings illustrativeof the preferred embodiment of the invention,

Figure 1 is a side elevation of the iinproved scale. Fig. 2 is a topplan view. Fig. 3 is a bottom plan view. Fig. 4 is a section on the line4-4 of Fig. 2. Fig. 5 is a section on the line 5-5 of Fig. 1.

The improved device comprises a casing 10 preferably in the form of awatch or small circular clock and provided with spaced sides arranged inparallel relations and with a suspending ring 11, the ring beingpreferably in the form of the ring portion of a watch. The casing 10 isprovided in its lower side, or in the side opposite to the ring 11, withan Opening 12 having a movable closure 13, the latter being preferablyslidably arranged, so that the Opening may be closed or opened asrequired. One of the flat faces of the casing 10 is provided withgraduations represented at 14 and representing pounds and fractions ofpounds. Any required number of the graduations may be employed but forordinary purposes the capacity of the scale will be limited to fourpounds, the usual limit for mail matter. For the convenience of theuser, it is considered advantageous to emboss a table of postal rates10' on the face of the dial.

Located within the casing 10 is a suitable frame 15 to which theweighing mechanism is connected. The frame 15 is detachably connected tothe casing by screws or other suitable fastening devices 16. The frame15 may be constructed in any suitable nanner, and includes in itsconstruction a main shaft or spindle 17 which extends at one end throughthe graduated face of the casing and is provided with a pointer 18 whichoperates over the graduations, as shown. The frame 15 likewise embracesin its construction two rods 19-20, the rods carrying the mechanisnwhereby the weight of the article will be transmitted to the shaft 17and the pointer 18. Mounted for oscillation upon the rod 20 is an arm 21having a gear segment 22 at its free end engaging a gear pinion 23 uponthe shaft 17. Mounted for rotation upon the rod 19 is another arm 24,and connected at 25 to the free end of the arn 24 is a coupling rod 26,with the upper end of the coupling rod connected at 27 to the arm 21near the segment 22. Connected at 28 to the rod 24 is a flexible memberor link 29, the latter eXtending normally through the Opening 12 of theoasing. Suspended from the lower end of the link 29 is a supportingdevice for the mail matter which is to be weighed. This supporting*device is' preferably formed from a single piece of wire bent intodouble hook-like form 30 at one end and with eyes 31 at the other end,the eyes engaging'in an aperture in the lower end of the fiexiblemember. The hook 30 provides means for suspendng the larger and morebulky articles,

while the sides of the hook formed by the wire member provide means forthe insertion of letters and like mailing matter, the friction betweenthe sides of the hook being suflicient to support such articles.

Extending transversely of the frame 15 at its upper side is another rod32, having a transverse aperture through which a pin 33 eXtends, the pinbeing threaded and provided with adjusting nuts upon each side of therod. At its lower endthe pin 32 is provided with a hook 34 to receivethe upper end of a spring 35, the lower end of the spring beingconnected at 36 to the arm 21. By threading the pin 33 and providing itwith the adjusting nuts the pin may be adjusted to control the tensionof the spring 35, and thus enable the spring to be adjusted to cause theaccurate operation of the weighing mechanism. The spring provides thenecessary balance to the weighing device, in the ordinary manner. Theaperture 12 is of sufficient size so that the suspending de- Vice 30 andthe link 29 may be folded into the casing and the slide 13 closed Whenthe scale is not in use.

As before stated, the casing Will be relatively small, not necessarilylarger than an ordinary Watch, and When not in use may be carried in thepocket, hence the necessity for the means Whereby the hook 30 and thelink 29 may be disposed within the casing when the scale is beingtransported.

The improved device is simple in construc tion, can be manufactured ofany suitable material and Will be found convenient for purposes ofWeighing mail matter, and may be readily transported 'in the pocket.

What is claimed is In a Weighing scale, a casing having a graduated dialand with an Opening in one of its walls, a frame secured in said casing,a shaft journaled in said frame and extending through the casing, apointer carried by Copies of this patent may be obtaied for five centseach, by addressing the arm intermediate the length of the latter, a 0

spring connected to maintain said arms yieldably in one position, meansfor adjusting said spring, a flexible member connected to said lastmentioned arm and extending through the casing aperture, and a support-35 ing,` device connected to said fleXible member.

In testmony whereof, We afliX our signatures in presence of twowtnesses.
